mmvdisk: Total capacity is the raw space before any vdisk set definitions.
mmvdisk: Free capacity is what remains for additional vdisk set definitions.
14. Allocate the new space by using the mmvdisk command set.
An example of adding the new storage to an existing file system is as follows:
a. Define a VDisk set that is tied to the existing recovery group. This example assumes that an
existing VDisk code is 8+2p (default), block-size is 4 MiB (default), and set-size is 80% (default).
Because the decluster array size is doubled after new 12 drives, the set-size is set to 40%
to keep the new VDisk size same as the original VDisk size. For information about non-default
configurations, see IBM Spectrum Scale RAID: Administration in IBM Elastic Storage Server
documentation.
# mmvdisk vdiskset define --vdisk-set vs_fs3200_2 --recovery-group ess3200_78E400K --code 8+2p --
block-size 4m --set-size 40%
mmvdisk: Vdisk set 'vs_fs3200_2' has been defined.
mmvdisk: Recovery group 'ess3200_78E400K' has been defined in vdisk set 'vs_fs3200_2'.

b. Create the newly defined VDisk set.
# mmvdisk vdiskset create --vdisk-set vs_fs3200_2
mmvdisk: 4 vdisks and 4 NSDs will be created in vdisk set 'vs_fs3200_2'.
